Safety detection method and device for safety door

The invention discloses a safety detection method and device for a safety door. The method comprises the steps that the state of a switch of the safety door and the opening and closing time of the switch are obtained; calculating the state change times of the switch within a preset time based on the switch opening and closing time; judging whether the state change frequency of the switch is greater than an upper threshold or less than a lower threshold, or whether the switch is not closed after the switch is turned on for preset time; and if yes, giving an alarm prompt. Safety alarming is achieved by analyzing the opening and closing state changes of the safety door, potential safety hazards of the safety door are reduced, and the running stability and safety of the cigarette making and tipping machine combination are improved. 本申请公开了一种安全门的安全检测方法及装置，方法包括：获取安全门的开关的状态以及开关开启、关闭的时间；基于开关开启和关闭的时间计算预设时间内开关的状态变化次数；判断开关的状态变化次数是否大于上限阈值或小于下限阈值，或开关开启后是否达到预定时间仍未关闭；若是，则发出报警提示。本申请通过分析安全门的开关状态变化实现安全报警，降低安全门的安全隐患，提高卷接机组的运行稳定性
